Interaction with Pressure Regulator Valve and Valve Components

The Fuel Supply Tube Assembly, part 4998736, is integral to the efficient operation of engine systems, particularly in conjunction with the Pressure Regulator Valve and Valve components.

When the Fuel Supply Tube Assembly is installed, it ensures a consistent and reliable flow of fuel from the tank to the engine’s fuel system. This assembly interfaces directly with the Pressure Regulator Valve, which modulates the fuel pressure to maintain optimal levels for combustion. The Valve, often part of the regulator assembly, controls the flow of fuel into and out of the regulator, ensuring that the pressure remains within specified parameters.

The interaction between the Fuel Supply Tube Assembly and these components is seamless. The assembly delivers fuel under pressure to the regulator, where the Pressure Regulator Valve adjusts the pressure as needed. The Valve then allows the regulated fuel to proceed to the injectors or carburetor, depending on the engine’s design. This system ensures that the engine receives a steady supply of fuel at the correct pressure, which is essential for performance and efficiency.
